Embodiments discussed herein refer to LiDAR systems and methods that enable substantially instantaneous power and frequency control over fiber lasers. The systems and methods can simultaneously control seed laser power and frequency and pump power and frequency to maintain relative constant ratios among each other to maintain a relatively constant excited state ion density of the fiber laser over time.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The system of claim 1, wherein the second output power is varied from the first output power based on a preconfigured output power setting or a power saving setting.
3. The system of claim 1, wherein the second output power is varied from the first output power while maintaining the second repetition rate the same as the first repetition rate.
4. The system of claim 1, wherein the first output power is greater than the second output power.
5. The system of claim 1, wherein the first output power is less than the second output power.
6. The system of claim 1, wherein the first portion of the FOV comprises an area of no interest; wherein the first output power is at the minimum output power; and wherein the second output power is at the maximum output power.
7. The system of claim 1, wherein the second repetition rate is varied from the first repetition rate based on a preconfigured scanning density setting.
8. The system of claim 1, wherein the second repetition rate is varied from the first repetition rate while maintaining the first output power and the second output power at substantially the same level.
9. The system of claim 1, wherein the first repetition rate is greater than the second repetition rate.
10. The system of claim 1, wherein the first repetition rate is less than the second repetition rate.
11. The system of claim 1, where proportionally varying the seed laser power of the seed laser and the pump power of the pump comprises maintaining a ratio of the pump power and the seed laser power constant when one or both of the second output power and the second repetition rate are varied from the first output power or the first repetition rate, respectively.
12. The system of claim 11, where proportionally varying the seed laser power of the seed laser and the pump power of the pump comprises simultaneously varying the pump power and the seed laser power based on the ratio of the pump power and the seed laser power.
14. The method of claim 13, wherein the second output power is varied from the first output power based on a preconfigured output power setting or a power saving setting.
15. The method of claim 13, wherein the second output power is varied from the first output power while maintaining the second repetition rate the same as the first repetition rate.
16. The method of claim 13, wherein the first output power is greater than the second output power.
17. The method of claim 13, wherein the first output power is less than the second output power.
18. The method of claim 13, wherein the first portion and the second portion of the FOV comprise an area of no interest; wherein the first output power is at the minimum output power; and wherein the second output power is at the maximum output power.
19. The method of claim 13, wherein the second repetition rate is varied from the first repetition rate based on a preconfigured scanning density setting.
20. The method of claim 13, wherein the second repetition rate is varied from the first repetition rate while maintaining the first output power and the second output power at substantially the same level.
21. The method of claim 13, wherein the first repetition rate is greater than the second repetition rate.
22. The method of claim 13, wherein the first repetition rate is less than the second repetition rate.
23. The method of claim 13, wherein proportionally varying the seed laser power and the pump power comprises maintaining a ratio of the pump power and the seed laser power constant when one or both of the second output power and the second repetition rate are varied from the first output power and the first repetition rate, respectively.
24. The method of claim 23, wherein proportionally varying the pump power and the seed laser power comprises simultaneously varying the pump power and the seed laser power based on the ratio of the pump power and the seed laser power.
